.加熱完畢后,關掉對應的加熱開關,將電壓調至零位。注意事項 電源箱通電前,外殼應可靠接地。 電源箱通電前,應先將電壓調整電位器逆時針旋至零位
開機后應先檢查冷卻風機是否正常工作,任何時候發現風機不正常工作都應立即停止使用電源箱,以免損壞可控硅等元件。插拔加熱棒前首先關掉該路的加熱開關。
.加熱開關為單極開關,故這只能控制加熱電壓的正極,關掉加熱開關后加熱棒后, 加熱棒還帶電。 本產品使用時應派專人操作,操作人員必需熟悉產品說名書后方可使用。
螺栓加熱器使用要求: 電加熱器使用耐熱絕緣資料容易吸潮,應放在通風干燥處,
若在運輸和儲運中吸入潮氣,應在使用前必須烘干,保證絕緣電阻不低與05兆歐方可使用。
使用前應檢查好被加熱螺栓的直徑及規格孔徑來確定加熱器的規格,以及長度和直徑,對號入座,切莫搞錯。 加熱器功率較大熱能性強,為確保工作人員的平安和延長加熱器的壽 命,應將加熱器插入螺栓孔內方可通電工作,抽出時必需切斷電源。 電加熱器是利用熱脹冷縮防爆電加(jia)熱(re)器的原理來達(da)到裝(zhuang)(zhuang)配螺(luo)栓(shuan)的專用設備,所(suo)以在(zai)(zai)使(shi)用加熱(re)器(qi)時(shi)機體(ti)溫(wen)(wen)(wen)度(du)應(ying)(ying)低于80℃以下為(wei)宜(yi)。機溫(wen)(wen)(wen)高會嚴重(zhong)影(ying)響裝(zhuang)(zhuang)配螺(luo)栓(shuan)。 使(shi)用電加熱(re)器(qi)加熱(re)時(shi)應(ying)(ying)掌握好時(shi)間(jian)和螺(luo)栓(shuan)的伸長系數(shu),位應(ying)(ying)及時(shi)抽出。以免讓螺(luo)絲冒過熱(re),造成(cheng)咬死。 電加熱(re)器(qi)在(zai)(zai)使(shi)用中(zhong)要求發熱(re)均勻不允許有(you)局部過熱(re)現象(xiang),每次使(shi)用時(shi)間(jian)為(wei)5-30分鐘,間(jian)斷加熱(re)情況(kuang)下,螺(luo)栓(shuan)中(zhong)心孔與(yu)電加熱(re)器(qi)的外徑總間(jian)隙在(zai)(zai)08-13mm為(wei)宜(yi)拆卸(xie)汽(qi)缸(gang)、導汽(qi)管保(bao)(bao)溫(wen)(wen)(wen):高中(zhong)壓外缸(gang)內(nei)壁溫(wen)(wen)(wen)度(du)120℃以下時(shi),可裝(zhuang)(zhuang)配汽(qi)缸(gang)保(bao)(bao)溫(wen)(wen)(wen)。
